I’ve just setup a local Maven repository so that I can share libraries I develop with other developers on campus. It was really easy, all you need is a filesystem that you can SCP to, you don’t need to install anything on it. Here’s how:
1. In the POM of the project you want to put in a repo:
<distributionManagement>
<downloadUrl>https://maven.repo.edu.au/</downloadUrl>
<repository>
<uniqueVersion>false</uniqueVersion>
<id>my-maven-repo</id>
<name>Enterprise Systems Maven Repository</name>
<url>scp://maven.repo.edu.au/file/system/path/</url>
<layout>default</layout>
</repository>
</distributionManagement>
You can also separate snapshot releases from point releases in two different repositories, by defining a snapshotRepository element as well as the repository element, same attributes as above.
2. Setup your username and password that will be writing to the repo:
2a. If you have not yet set a master password for Maven, you need to create one. If you have done this already, skip to 2c.
mvn --encrypt-master-password masterpasswordhere
returns:
{4utE9D2jMkQH9K0Lw7YuUnHkfCkZ3TtX55sWq1d2Ink=}
2b. Create a file .m2/settings-security.xml with that password:
<settingsSecurity>
<master>{4utE9D2jMkQH9K0Lw7YuUnHkfCkZ3TtX55sWq1d2Ink=}</master>
</settingsSecurity>
2c. Encrypt your password you are going to use for pushing to this repository:
mvn --encrypt-password hello
returns:
{g+cS+/xuAiEH87xfrsRmWIix5+ZtecvNAIzXDyzqD/E=}
2d. In .m2/settings.xml add a server block with that password, and matching id for the repo:
<servers> ....
<server>
<id>my-maven-repo</id>
<username>myusername</username>
<password>{g+cS+/xuAiEH87xfrsRmWIix5+ZtecvNAIzXDyzqD/E=}</password>
</server> ....
</servers>
3. Build and deploy your project to the repo:
mvn clean install source:jar javadoc:jar deploy
After it builds you should see it uploading the artifacts.
4. Now, in the POM of another project, you can set up your new maven repo as a repository to search and pull artifacts from:
<repositories>
<repository>
<id>my-maven-repo</id>
<url>https://maven.repo.edu.au/</url>
<snapshots>
<enabled>true</enabled>
</snapshots>
<releases>
<enabled>true</enabled>
</releases>
</repository>
</repositories>
